Thanks. I’ve been playing with jet sizes all along depending on the track. So yes, that could be true. As far as the water level, I fill it on top of the manifold with the air bleed open until all the air is out. Is it possible I still have trapped air ?
I had a small block in it prior and never had this problem.
We had this motor in a 23 T-bucket and it ran hot. It wasn’t until we put an electric pusher fan along with the engine fan that it finally ran cool. On the Willys, I can’t run an engine fan and I can’t get another electric one on the motor side of the radiator due to space restrictions.
